Algodystrophy

Definition

Algodystrophy (or algoneurodystrophy) is characterized by jointpain following a trauma suffered by the joint in question. It is a highly debilitating disease, as it is very painful and difficult to treat. It mainly affects people between 35 and 65, but can also affect other age groups.
This type of disease usually occurs after a physical shock, such as a sprained ligament or surgical intervention, but remains completely unpredictable as it can also occur for no apparent reason.

Symptoms

Algodystrophy is characterized by:

widespread pain and sometimes deep-set burning or discharge;

functional impairment (decreased movement or inability to use the concerned area, mainly because of the pain it causes);

a very slow and spontaneous improvement, however progressive and generally leaving no sequelae.

Diagnosis

The diagnosis of algodystrophy is difficult, and it is usually done by elimination, that is to say, after excluding other diagnoses potentially causing the same symptoms. Clinical signs are rarely significant enough to help establish a firm diagnosis. Additional tests are a good indication, but not sufficient either.
We can finally diagnose when sufficient evidence is found such as:

a history of trauma or operations;

a heightened and persistent pain in reaction to the same light stimulation;

Evolution

It is not possible to prevent and algodystrophy because we do not know its exact causes. However, we know that it tends to disappear spontaneously, usually within two years after its occurrence.
It usually leaves no sequelae except when it lasts longer than two years. In this case there is joint stiffness and muscle weakness, which is sometimes accompanied by pain.
